citizen of the United States, and a resident oi ll'iikinshurg in ti 10 county of Allegheny and State of lcin'isvlvania, have invented a new and useful improvement: in Hangers" and Clanips for li'ircs and Cables of which the following ii-a a specification.

My invcition rcla porting Qltttl'lti line tes to ineans vtor supconductors and it has tor its object to provide an improved clainptrolley conductor may ing device whereby a be sinipl -xainl durably support.

Myiniprove'd clani or cross wi secured to a suitable v ping device specially adapted for use with grooved trolley con-1 dun-tors that are suspended from messenger wires or ciibles but its use is not liinited in this regard and it may be employed in connection with condi'irtors 0i! circular cross 5 tion tha are supported, .troin bracl-iet arms known practice tor low potential lines.

The n'icinber comprises a hollow sleeve ll which is partially cl oscd at one end, lv eing provided with an opening 12 through which the extremity of the rod 3 may extend. The

member 8 is similar to the cable 2 but its to the member 7 closeother extremity is provided with an inwardly extending projection 1.3 which is ser the extremity of the ew-threaded to receive rod 3.

The detailsot construction of the clamps l and 5 may best be understood by reference to Figs. 3 to it), inclusive, in which the portions ot tlie chunos are de--igrnatcd by the H24 iii, reference characters as those on:- ployed in l igsv l and it will be ()bF-itlYC-ti that a considerable adjuntnn nt in the lcn th of the hanger may be cti'ectcd, since the hanger rod screw threaded tor a material distance near: its

ends; rtnothcr advantage of my improved hair .2 hes in the tact that the trolley conductor may be released from its clamp Without disturbing the messenger cable clamp.

It is conceivable that 'variation in the size and arrangement oli parts may be cficctcd within the scope of my invention and I desire that only such limitations shall be iniposed as are indicated in the appended claims.

1 claim as my invention:

1. ii clamp for wires or cables comprising a hanger rod, two couinleineotary jaw incinbors ha ving grooves in which a wire or cable may be supported, one oi said jaw members having; a substantially tubular body portion partially closed at one end to form an open ing through which the end of "the rod tends and the other member being provided with a tapped sleeve projection which extends into the tubular body of the first incinbc' and is engaged by the cxtrvu'iity of the hanger rod and a set-nut which is forced against the outer surface of the partially closed end of the tubular body portion to produce a clamping action bet ween the jaw members.

2. A clamp for wires or cables comprising a hanger rod, two eonipleincntary jaw inenr bers having hook projections adapted to engage a grooved conductor, one of said members having a substantially tubular body portion partially closed at one end to form an opening through which the end of I the rod extends, the other member being prohollow body portion and a beveled outer end surface and the other of which has a projection located within said hollow body portion and into which the end of the rod is screwed, and a nut mounted on the rod to engage the beveled end surface.

4. A hanger comprising a rod having a scnew-threaded end, a clamping member having a hollow body portion and a beveled outer end surface, a clamping member having a projection located in the said hollow body portion to receive the end of the rod and provided with a shoulder to be engaged by one side of the other member, and a nut mounted on the rod to engage the beveled surface.

5. A hanger comprising a rod having a sci-ew-threaded end, a clamping member having a hollow body portion and a beveled end surface, a clamping member having a laterally projecting lug into which the end of the rod is screwed, and a nut mounted on the rod to engage said beveled end surface 40 to drawthe members together.

6. The combination with a support, of a 7. The combination with a supporting member, of a pair of clamping members each having a transversely extending member, one of said members being carried by the support and the other carried on the first member and fulcrumed thereon, said transversely extending members each having an opening therein to permit the support to pass therethrough.

In testimony whereof I have hereunto subscribed my name this 29th day of August, 1907.
